Subject: Revert "drm: Add and handle new aspect ratios in DRM layer"

Revert "drm: Add and handle new aspect ratios in DRM layer"

This reverts commit a68362fe3e84fcbedd49939aa200519aa5410135.

Adding new mode flags willy nilly breaks existing userspace. We need to
coordinate this better, potentially with a new client cap that only
exposes the aspect ratio flags when userspace is prepared for them
(similar to what we do with stereo 3D modes).
